To all whom t may concern.: Be it known that I, CARL N. ROBINSON, acitizen of the United States of America, re-

siding at Pawlet,in the county of Rutland and i State of Vermont, haveinvented certain new and useful Improvements in Tools for RemovingSections from Scythe or SickleBars; and I do hereby declare thefollowing to be a full, clear, and exact description o the invention,such as will enable others illedin the art to which it appertains tomake and use the same, reference being had to the accompanying drawing,and to lettersy of refer,

ence marked thereon, which forms a partof this specification.

This invention relatesv to certain new and' useful improvements in toolsfor removing sections from scythc or sickle bars, the object of myimprovement being to provide a cheap, simple, and eifectivetool of suchconstruction that it may be used in connection section from the Scytheor sickle bar and while so doing will sever the rivets which connect theparts. p

In the accompanying drawing, which illustrates my invention, the Vligureis a perspective view showing the tool and manner of sup sickle bar tobe operated upon. A refers toa suitable support, which in practice maybe a vise, and upon the same the Scythe or sickle bar comprising the barand knife sections are p1aced,so that the bar B will rest .upon one ofthe jaws of the .vise and the knives or sections C depend between saidjaws, so that the knives will be maintained in a vertical position. barand the sectionsor knives are held in en gagement with each other byrivets c.

The scythe or sickle har B is usually made of soft steel' while thesections are of hard ory tempered steel and the rivets of Norway iron,and the usual method of removing the seetions from the bar is by the useof" a cold. chisel or punch. -This manner of' removing The scythe orsickle the rivets is objectionable, as the bar is usually placed flatand the metal being of less strength in one direction than the other thebar is liable to be bent. Vith my improved tool the'liability of bendingis avoided and the knives or sections can be removed rapidly withoutinjury either to the sections or to the seythe or sickle bar.

D refers to the tool or implement, which is made up of a single piece ofmetal and is provided with a recess d, the portions on each side of therecess bei-ngof dierent lengths, one part, d', being substantially thesame length as thewidth of the scythe or sickle bar,while the otherportion, d2, is considerably shorter.A l'lhe part d2 has its lower endflat- .tened for engagement with the straight edge yof the section, andthe upper portion of the' tool is made after. the manner of a punch.

In operation the scythe orvsickle bar with the knives or sectionsthereon is supported by avise. vThe tool isthcn placed over the scythe4or sickle bar and the section thereon above one of the rivets. Now byhammering upon the upper end of thel tool the section will -be forceddownward and will4 sever the rivets. The depending member di of the toolwill serve as a guide, so that the tool will not slip off in use.
